I would like to sort a list of strings in python, however digits included in those string should be omitted by the sorting script. Example of such list can be found below:

QUESTION
I am looking for a way to naturally sort Django's QuerySets. I found a similar question, but it did not focus on QuerySets. Instead they are doing it directly in Python.
So here is my problem. Let's say I have this model:

Answered 2019-Dec-06 at 17:27I'm assuming your signature field follows this pattern: AAA 123
letters followed by a space followed by numbers (int).
QUESTION
I've generated many image-files (PNG) within a folder. Each have names akin to "img0.png", "img1.png", ..., "img123164971.png" etc. The order of these images matter to me, and the numerical part represent the order I need to retrieve them before I add them to a html-form.
This question closely gives me a solution: Does Python have a built in function for string natural sort?
But I'm not entirely sure how to incorporate it into my specific code:
...ANSWER
Answered 2019-Jan-22 at 23:54Assuming you really want to have things "naturally sorted" strictly by the name of the individual file, as opposed to the full path (e.g., so "zzz/image01.png" comes before "aaa/image99.png"), (EDIT: I see now from the comments that this isn't the case) one way to do this is create an ordered dictionary where the keys are the filenames, and the values are the "" tags you're ultimately creating. Then do a natural sort of the dictionary keys, and return a list of the corresponding values.
So using a simple list of 3 made-up files and adding a twist to the original natural_sort, function:
QUESTION
I have a function in python which returns a tuple of a given key for the Natural-Sort/Human algorithm.
See fake _human_key.
But I need this to change this to replace German umlauts by their standard alphabetical characters.
Long story short, I want to get rid of Ä, Ö, Ü, ß
for the sorting.
Also, the case should not be considered. A small d
should have the same priority as a capital D
...
For the umlauts I am utilizing the replace-function which seems a pretty awkward way to do it... :-/ I have no better idea... Any suggestions?
Also I am not able to rewrite this to get rid of the case sensitiveness...
So far I have:

I would like to ask how to sort a List
in descending order using the Natural Sort Comparer library.
I would like to ask if you someone have use this library

?
This is the code snippets for ascending
...ANSWER
Answered 2018-Dec-04 at 11:21You have two options:
- Horrible, never do this: use the ascending order and then simply call
Reverse()
method (I'm only listing this option as a warning because, believe it or not, I've seen it more than once in production code). - The good way: Implement an
IComparer
that simply returns the negative of the "ascending" comparer (or switches the argument order) and pass it into your sorting method.
But nº2 is already built in the framework for you; its the extension method OrderByDescending
